Floyd Rose FRPTUFB42 Pro Fat Tungsten Sustain Block 42 mm: Ultimate sustain upgrade

The Floyd Rose FRPTUFB42 Pro Fat Tungsten Sustain Block 42 mm is engineered to elevate the sustain and clarity of any tremolo-equipped electric guitar. This model fits directly into German-made Floyd Rose Pro systems, utilizing high-density tungsten—one of the heaviest materials in guitar hardware. For guitarists craving a dramatic leap in brightness and sustain, the block brings a noticeable improvement to your instrument. Less string vibration is lost through the springs due to the tungsten construction, so you get more resonance preserved in your strings and bridge for a livelier, more expressive sound. Those familiar with basic bridge setup will find installation straightforward.

Extra mass and density for powerful tone

What makes the FRPTUFB42 unique is its use of tungsten, which is four times denser than titanium and twice as dense as brass. Such added mass translates to improved sustain and sharper, more defined tones, a difference especially apparent during solos and extended chords. The 12.75 mm thick body is tailored to deliver the fullest tonal advantages from your Floyd Rose Pro system.

Who is it for?

This model suits guitarists using German-made Floyd Rose Pro bridges who want to push their sound further. The FRPTUFB42 is the choice for dedicated players searching for tangible improvements in sustain, note clarity, and articulation. Those upgrading from stock or brass blocks will find the resulting sound noticeably brighter and longer-lasting, making it especially popular among modern rock and metal musicians seeking hardware that meets demanding standards.
